Letters Patent No. 85,155, dated December 22, 1868.

IMPROVED MACHINE FOR WASHING- DISHES.

To all whom it may concern:

Be it known that we, L. R. WITHERELL and E. A. WVITHERELL, of Galesburg, in the county of Knox, and State of Illinois, have invented certain new and useful Improvements in Dish-Washing Machines; and we do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawings, making a part of this specification, in which-- Figure 1 is a vertical central sectional view.

Figure 2 is a side elevation of a part of'thc mcchine.

Figures 3 and 4 are top plans of racks, for carrying dishes, 860., while washing.

Similar letters of reference indicate similar parts in all-the drawings.

' The nature of this invention relates to improvements in machinery for washing dishes; and

The invention consists in an arrangement of racks for holding dishes, plates, 860., and suit-able mechanism for turning them and exposing all sidcsto the action of boiling water discharged among them through jets in a pipe connected with a force-pump, which is attached to one side of the vessel containing the dishes, and which is operated by the same crank which revolves the racks.

Letter A is a cylindrical-shaped vessel, constructed of any suitable material, and of any desirable size, and provided with lid B, hinged at O, for convenient communication with the inside of the vessel A.

Letter in, fig. 1, is an upright shaft, supported in the socket a, in the bottom of the vessel A, in a manner allowing it to revolve freely.

Letter It is a disk, carried in a horizontal position on the top of shaft m.

Letter F is a shaft, with bearings at P and V", and carrying on its outer end the crank E and handle t, for operating the machine.

Letter G is a worm on the shaft F, gearing with the worm-Wheel J, on the shaft in, and communicating the rotary motion of shaft F to thedisk R.

Letter T represents racks; a side view shown at fig. 1, and top view of the two styles, shown at figs. 3 and 4. These racks are set on'the disk It, and held in place by pins S S, or their equivalent. The style of rack shown at fig. 3 is intended more particularly for dishes, which are stood on their edges in the spaces;

while the style at ii 4 is intended for cups and saucers,

and similar-shaped vessels, which may be laid in with their lnoutlis or open ends outward; and the centre spaces T" T", fig. 4, are intended for knives and forks, 860., which may he stood on end. A Letter 1) represents a case, attached to the side oi the vessel A, and contains a double-acting forcepump. The piston Z, of the three-pump, is connected with and operated by the cranks E, by means of the comn-cting-rod w. The suction-pipe g, of the forcepmnp, communicates with and draws the supply of water i'rom The bottom of the vessel A.

Fig. 2 is a side view, of the pump-case D and connections, taken from the 'po'intlQ, fig. 1.

Letter 0', fig-2, is the discharge-pipe of the pump. This pipe c".oommunicates, by stop cock a and pipe-e, with the jet-pipe X; the pipe X being provided with any. desired series of holes, 9 y, and standing in a vertical position inside of the vessel A.

Letter his a hose and nozzle, which may be attached to the. discharge-pipe, if desired, and communicates therewith by means of stop-cock a".

Letter P is a cock, for drawing ofi thcwatcr when desired.

The manner of operating my machine is as follows:

The dishes, 850., being placed on the rack, and the rack. put in'position on the disk 1t, and water, being heated to 212, is poured in the vessel A-,'to fill it nearly to the disk It. The lid B is closed, and the pump, set in operation by thc'crank E, will draw its supply from the water in the vessel A, and discharge it with great propulsive power through the y, in pipe. X, among the dishes, the same motion of the crank E revolving at the same time the disk It and rack T, and presenting, by turns,'all sides of the arti- 'cles being washed, to. the mechanical action of the propelled jets of boiling water.

The water being many degrees hotter than can be from below, while using the same supply of water over'and over.

If desired, the stop-cock a, maybe closed, and the stop-cock a," opened, and waterfrom the vessel A, through the hose h, be used-for washing carriages, windows, 85c.

What we claim as our invention, and desire to se cure by Letters Patent, is

1. The arrangement of disk R, rack. T, shaft m, socket a, worm-wheel J, shaft F, worm Gr,- and bearings P and 1 when used in dish-washing machines, substantially as described, and for the purpose set forth.

2. The combination and arrangement of the vessel A, pump D, pipc X, crank E, shaft d5, Worm G, pinion J, shaft m, disk It, and rack T, substantially as described, and for the purpose set forth.
